I know the symptoms of PMR are usually worse at night and in the morning - but does anyone know why? I have been unable to find any information regarding the cause of this phenomena - yet they are (at least morning stiffness is) important diagnostic criteria for PMR. Just would like to understand this, as well as satisfy my curiosity. Thanks in advance for any light you can shed on this subject.
Please help.
Thanks!
I didn't find the right solution from the Internet.
